[Eric Pettersen]

User attempted to attach session, but it was too large

[Greg Couch]

Where was that error reported? I searched for "but it was too large" in the ChimeraX source, the ChimeraX production and preview web sites, /usr/lib64/python2.7, /usr/lib/python2.7, and /usr/local/lib/python2.7 (because the the cgi-bin chimerax_bug_report.py uses python2), and the rbvi-production-ssl_error_log.

I like to increase the file size limit, so it will possible to see this bug. The bug appears to be with the pypi lz4 module, so we might have to wait for an upstream fix.

[Eric Pettersen]

The text, as per the automated comment just above mine, is "is larger than the allowed attachment size", which is a Trac limitation -- and is controlled by the "max_size" setting in the "attachment" section of the trac.ini file.

[Greg Couch]

Any objection to raising the limit from 128Mbytes to 512Mbytes?

[Eric Pettersen]

*I* have no objection, though Scooter was the one that chose the limit -- so if you change it you might want to shoot him an email so that he can eventually weigh in once he's back on his feet.

[Greg Couch]

done.
